chk_cyrus — Cyrus IMAP documentation

Perform a consistency check of the Cyrus IMAP mail spool.


chk_cyrus [ -C config-file ] [ -P partition | -M mailbox ]


chk_cyrus is used to perform a consistency check on the cyrus datastore, and output a list of files/directories that are expected to exist, but do not.  Status messages are output to stderr, the list of files/directories is output to stdout.  This list can be passed to a backup program to aid a partial restoration, for instance.

chk_cyrus reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.


-C config-file

Use the specified configuration file config-file rather than the default imapd.conf(5).

-P partition

Limit to partition partition.  May not be specified with -M.

-M mailbox

Only check mailbox mailbox.  May not be specified with -P.


The mailbox must be specified in the internal format, so rather than specifying user/john/, you will want to specify!user.john.Trash.


chk_cyrus -P default

Perform consistency checks on default partition.

chk_cyrus -C /usr/local/etc/imapd-slot1.conf -P default

Perform consistency checks on default partition using specified configuration file.

chk_cyrus -M user.marysmith

Perform consistency checks on mailbox user.marysmith.
